Spray Foam Insulation

Demilec Approved Applicator ThermoSealLogo-215Foam-Lok-Certified

Polyurethane Spray Foam Insulation provides some of the best insulating performance possible by effectively minimizing the culprits that cause heat gain or loss in a home: convection, conduction, radiation, air infiltration, air intrusion, and moisture accumulation. Good Life Energy Savers uses best-in-class open and closed-cell spray foam insulation products that deliver significant energy savings and increased comfort.

Our high performance polyurethane spray foam is applied by installation professionals who are approved applicators. The foam is applied to walls, attics, basements, and crawls as a heated liquid which then quickly expands, completely filling every open space. It cures within seconds providing a thermal, sound and condensation barrier in a single application without seams or gaps.

R-Value & Air Leakage vs Fiberglass

Fiberglass batts will not stop air leakage. Spray foam will stop air leakage dead. Spray foam is also mold and moisture resistant unlike fiberglass. Fiberglass batts have an R-value of about 3.5 (1-inch thickness) but this is not a “true” R-value since there is no air seal. Most Open Cell Spray foams have a true R-value of about 4.0 per inch and Closed Cell has an R-value over 6 per inch. Fiberglass batts can sag over time and can leave gaps and small sections uninsulated. Spray foam completely adheres to wood and sheathing; the result is a permanent barrier to heat loss and air entry. In addition, spray foam will add strength to the structure where fiberglass batts will not.


Spray Foam Insulation can be used in new construction and additions as well as in older homes as a retrofit product.  For new homes, we typically use open and closed cell polyurethane spray foam to spray walls, attic rafters and roof systems, as well as basements and crawl spaces.   In older homes, these polyurethane spray foams in the attic and basements or crawl spaces are a great complement to our Tripolymer injection foam in the exterior walls.

A Tight Thermal Envelope That  Means Year-Round Comfort for Your Family

In a typical home, up to 50% of conditioned air is lost from gaps thus resulting in excessive heating and cooling bills. Our spray foam insulation system performs proficiently, dramatically reducing air leaks which results in a consistently comfortable home. It seals the nooks and crannies where dust and pollen can enter the home, creating a much healthier living environment. Our spray foam also helps prevent condensation, which is key in averting mold growth.  Once applied, spray foam forms the foundation of a virtually airtight thermal envelope.

Bottom Line Benefits

Not only is a Good Life Energy Savers insulated home ultra energy-efficient, it will also save you money, provide a far more comfortable living space, and is ultimately worth more than the typically built home.  Finally, your high performance home will also play a significant role in reducing our nation’s need for foreign oil.

Demilec Approved Applicator


Good Life Energy Savers uses a variety of foams that can lower your energy bill.  We will decide on the best one for your home during the free consultation, answering any questions you may have.

We use various forms of Spray Foam, with the main choices being open or closed cell. Open cell foams tend to be softer, and it usually takes very little of this product to fill a space. It can also act as a good sound barrier, but the downside is that it is not as strong as the closed cell foam, which is unlikely to leak air or water.

Here are some of the differences between the spray foams that we use, We will use our expertise to recommend the best one for your home.

Open Cell (Example: Demilec’s Sealection Agribalance Polyurethane Spray Foam)

With more than 20% renewable content, Demilec’s Agribalance open cell polyurethane spray foam exceeds the US minimum standards for renewable content and is rated as one of the highest Green insulation products on the market.  It has one of the highest R Values (R = resistance to heat) for open cell foam – one inch of Agribalance has a 4.5 R Value.

With any open cell spray foam, tiny cells of the foam are broken and air fills all of the “open” space inside the material. This makes the foam softer feeling than closed-cell foam.


  • more economical yield than closed cell
  • excellent thermal insulating and air barrier properties
  • effective as a sound barrier


  • softer than closed cell
  • “spongier” appearance than closed cell
  • lower strength and rigidity than closed-cell foams

Closed Cell (Example: Demilec’s Heatlok Soy Polyurethane Spray Foam)

Demilec Heatlok Soy closed cell polyurethane spray foam is the most technologically advanced and efficient form of insulation for improving the performance of a bulding.  A single application creates an air, moisture, and vapor barrier that adds to the building’s structural integrity. Closed cell spray foam is almost always preferred in basements and crawl spaces, because of its vapor resistance characteristices, and can also be used on walls and attics.

The tiny foam cells of closed cell spray foam are closed and packed together. They are filled with a gas that helps the foam rise and expand and become a greater insulator. Closed cell foam would be a good choice where small framing sizes need the greatest R-value per inch possible. One inch of Demilec Heatlok Soy has an R Value of 7.4. Closed cell foam is also an excellent vapor  barrier.  Building Codes stipulate that a vapor barrier must have a water vapor permeance less than 1 perm.  Independent test show that Heatlok Soy excedes these standards by as much as 38 percent.


  • strength
  • higher R-value
  • greater resistance to the leakage of air or water vapor


  • Denser; requires more material
